Thanks for the report. Could you provide us with the exact json/store data you're using to create the chart? I'm trying to reproduce the example and for now I will try to use something that matches what's shown in the grid, but I would really appreciate if you could give me the exact dataset for the example.

The axes are working for me. I'm not sure if this is because I'm working on a newer build or because the data from the example is different. Could you try this use-case and tell me whether it works for you too?
